In the progression of Drain valve manufacturers' technology, Trident’s condensate sensing type automatic drain valves are the newest. Quintessentially useful and reliable, these valves sense the condensate level for activation instead of working through the cycle timer. The simplest form of a desiccant kind of Gas or Regenerative heatless desiccant dryer is the heatless compressed one. It can achieve a dew point of -40°C for the compressed air systems as well as the other applications of gas and/or air dryers.
